POLYMER COMPOSITION COMPRISING ORGANIC MATERIAL-MODIFIED PHILOSILICATE, FILM, GAS BARRIER FILM AND SUBSTRATE AND IMAGE DISPLAY ELEMENT USING THOSE

摘要

PROBLEM TO BE SOLVED: To provide a polymer composition having both of the excellent heat resistance and the excellent gas barrier property and a film composed of the polymer composition and to provide a gas barrier film having the film and to provide a substrate and an image display element having excellent fineness and durability.

SOLUTION: The present invention provides the polymer comprising an organic material-modified philosilicate having 190-350°C decomposition-starting temperature in a polymer having 120-400°C glass transition temperature of the polymer alone, the film composed of the polymer composition, the gas barrier film having an organic-inorganic hybrid layer and obtained by a sol-gel method, a substrate having the film or the gas barrier film and the image display element having at least anode, a luminescent organic thin film layer and a cathode on the film or the bas barrier film.
